Definitions

• the invention relates to a mobile work machine, in particular a truck-mounted concrete pump, with a chassis and walk-on platforms that are located on support brackets that project laterally on the chassis.
• the invention has for its object to improve the mobile work machine of the type mentioned in the platform area in such a way that the production is simplified and the storage is reduced and that the assembly on the support brackets and the connection with attachments is simplified and yet made more variable.
• the solution according to the invention is primarily based on the idea that the platforms consist of hollow profile rails which rest on the support brackets with a hollow professional wall pointing downward and are detachably connected to them.
• the hollow profile rails are expediently designed as extruded parts made of aluminum. In principle, it is also possible to produce the hollow profile rails as continuous cast parts made of plastic or compound material.
• the hollow profile rails have undercut longitudinal grooves which are open at the bottom for receiving slot nuts provided with screw holes or pegs.
• the sliding blocks can be placed anywhere on the longitudinal grooves and are primarily intended for fastening the platforms to the support brackets.
• the support brackets are designed as cross-sectionally U-shaped supports, which are screwed to the hollow profile rails at their upward-pointing connecting web via slot nuts.
• individual groups of sliding blocks can be provided for fixing box-shaped or magazine-shaped components on the underside of the platform.
• Individual grooves or hollow chambers of the hollow profile rails are intended for receiving lines, in particular electrical, pneumatic or hydraulic lines.
• the hollow profile rails can also be divided in the longitudinal direction. In particular, it is possible to separate two platform parts from one another by means of an intermediate piece, which is intended, for example, to receive a pivotable or telescopic support leg.
• the hollow profile rails expediently carry a non-slip structured tread on their upper side.
• a ladder is provided at the end of the platform, which is provided with a tubular handrail, which is connected via an upper convexly curved handrail section to a rear tubular support spar and which, together with the support spar, delimits a free space , in which at least one housing, in particular for accommodating an operating device, is arranged.
• the lines leading to the housing in particular electrical, pneumatic or hydraulic lines, can be within the Handrail and / or the support bar can be arranged protected.
• the at least one housing is expediently fixed to the support bar.
• a preferred embodiment of the invention provides that the handrail and the support bar form a one-piece, essentially U-shaped bent metal tube.
• the ascent stairs are height-adjustable or flexible, at least in the area of their lowest stairs.
• Figure 1 is a side view of a truck-mounted concrete pump with platforms arranged on the side of the chassis;
• FIG. 2a to c show a plan view, a side view and a section of a platform arranged on the chassis in an enlarged view compared to FIG. 1;
• FIG. 3 shows a section through the platform made up of a plurality of hollow profile rails without a console corresponding to FIG. 2c;
• FIG. 4a shows a section through the platform arranged on the chassis in an enlarged view compared to FIG. 2c;
• FIG. 4b shows a representation corresponding to FIG. 4a with an attachment part fastened to the base side
• FIG. 5a and b show two different side views of a handrail with a support bar for the ascending stairs according to FIG. 1.
• the truck-mounted concrete pump shown in FIG. 1 has a chassis 10, a thick matter pump 12 arranged on the chassis with material feed container 14 and placing boom 16, front and rear support legs 18, 20 which can be extended on the chassis, two on the side next to the thick matter pump 12 and the placing boom 16
• Platforms 22 arranged on the chassis and a rear ascent 24 leading to the platforms.
• the platforms 22 rest on support brackets 26, which are welded at a distance from one another on associated longitudinal members 28 of the chassis 10 and project laterally beyond them.
• the platforms 22 consist of hollow profile rails 30, 30 ', 32 which rest with their downwardly facing profile wall 34 on the support brackets 26 and are detachably connected to them.
• three hollow profile rails 30, 30 'and 32 are connected to one another in a positive and non-positive manner on longitudinal abutting edges 36, 38.
• the connection represents a type of tongue and groove connection in the area of the abutting edges 36, 38.
• an inner end panel 42 is placed on the abutting edge 40 of the inner profile rail 30 according to the same tongue and groove principle.
• the two inner hollow profile rails 30, 30 ' are identical in construction, while the outer hollow profile rail 32 has an end profile 44 with an outer panel 46.
• the outer panel is suitable for fastening external position lights, the electrical feed lines of which can be guided along the inside of the end panel 46 of the platform. Furthermore, in the area of the end profile 44 and the outer panel 46, a swivel which can be pivoted through 180 ° and can be locked in the upward-pointing position can be articulated.
• the hollow profile strips 30, 30 ', 30 ′′ have undercut longitudinal grooves 50 which are open at the bottom for receiving nut blocks 52 provided with screw bores or tenons.
• the nut blocks 52 can be positioned at any desired locations on the longitudinal grooves the slot nuts 52 located on the longitudinal grooves 50 are used once to fix the hollow profile rails 30, 30 ', 32 forming the platforms the support brackets 26 used.
• the support brackets 26 are designed as cross-sectionally U-shaped supports, which are screwed to the hollow profile rails at their upward-pointing connecting web 54 by means of screws 56 via the sliding blocks 52 (cf. FIG. 4a). As can be seen from FIG.
• attachments 58 such as tool boxes, magazines or the like, can also be fixed from below by means of screws 56 via the longitudinal grooves 50 and the sliding blocks 52.
• the hollow chambers 48 and the longitudinal grooves 50 are also suitable for accommodating lines, in particular electrical, pneumatic or hydraulic lines, which have to be laid along the chassis of the truck-mounted concrete pump.
• the platform is divided into two parts in the longitudinal direction, which are separated from one another by an intermediate piece 60.
• the intermediate piece 60 has a recess which is open to the outside and can be closed by a slide for receiving the rear support leg 20 in the pivoted-in end position.
• the platform 22 is delimited by a downward-facing end plate 64, which is composed of the same hollow profile rails 30, 30 ', 32 as the platform.
• the end plate 64 is screwed at the connection point 66 to the hollow profile rails of the platform 22 either at right angles (as shown) or with a miter.
• Climbing stairs 24 are connected to end plate 64 and are laterally delimited by handrails 68.
• the handrails 68 are connected in one piece via an upper curved handrail part 70 with a rear support bar 72.
• the handrail 68, the handrail aggregate 70 and the support bar 72 form a U-shaped curved metal tube which is screwed to the ascending stairs at the free ends and delimits a free space 74 between the handrail 68 and the support bar 72.
• On the support bar 72 there is a control box 76 and a case-like housing 78 for storing documents and writing materials. attached tools that largely take advantage of the space 74 for their accommodation.
• the lines leading to the control box 76 are led through the free interior of the tubular handrail 78.
